-RlNe-FRAME SPINDLE.

SPECIFICATION forming part of Letters Patent N 0. 731,111, dated June 16, 1903.

Application tiled September 22, 1902. Serial No. 124,274. (No model.)

T0 all whom, it may concern:

Beit known that I, THOMAS ERNEST LEIGH, of Heaton Chapel, Manchester, in the county of Lancaster, England, have invented certain new and useful Improvements in the Spindles of Ring-Frames, of which the following is a specification.

My invention relates to that form of spindle used in ring-spinningand doubliug,which, as in the Rabbeth'type, is formed with a bolster acting as a reservoir for oil, as well as a support o1' bearing for the spindle.

The purpose of my invention is to provide a means of supplying the said bolster with oil from a suitable outside receptacle in which it is stored and of discharging Vthe oil contained in the bolster without necessitating the use of pumps or the removal of the spindle.

Reference may be made to the accompanying drawings, wherein- Figure l is a sectional View of the lower portion of the bolster with my invention attached. Fig. 2 is a front elevation of the same, and Fig. 3 is a sectional view of a modiiication of my invention.

The bolster-casingA contains, as usual, the inner bearing-tube B, carrying the spindle C, the space surrounding the tube B and the lower space A of the bolster being ordinarily filled with oil. I bore a hole D inthe bottom of the bolster-case and thread the same. Into the hole D, I screw the screwed spigot E of a hollow tapered barrel, the said spigot E being bored through, so as to provide a channel for the oil to ow into and out of the space A. The barrel E is accurately bored internally, and ahollow plug E is correspondingly turned, so as to .tit accurately the said barrel. The plug F forms a part of the tube or reservoir G,with which it communicates. At the point F the plug is formed with a ring groove, and holes are also formed in the plug F to enable the oil to flow freely to and from the space A and the reservoir G. The plug F is retained in position by a washer H and nut H', screwed onto a threaded nipple F2,which projects through the barrel E.

It will be easily seen that the reservoir G can be rotated in the barrel E, so that its open end can either be up or down. When the said reservoir is turned downward, the oil contained within it is freely discharged, together with that contained in the bolsterspace A. When this has taken place, the reservoir is turned upward into the position shown in the drawings and is reiilled with oil, which speedily Hows into the bolster until it assumes the level of that in the reservoir.

Instead of screwing the barrel E into the bottom of the bolster I may, as shown in Fig. 8, bore the bolster itself with taper holesE E, one in each wall of the bolster-case A, and lit therein the plug F, attached, as before, to the reservoir G. The operation of the device is in each case the same.

It'will be seen that the rotative connection between the reservoir A and the supplemental reservoir G enables the latter to be turned from upper to lower position, so that the oil .in the former may discharge through the latter, and when the supplemental reservoir is then returned to upper position' oil which is poured into the latter will run freely into the bolster-reservoir A.

Having thus described my said invention,

I claim as new and desire to secure by Letters Patent- 1. The combination with the bolster or spin dle case having a threaded hole bored in its base, of a hollow barrel internally tapered and screwed into said threaded hole, and a supplemental reservoir having a correspondingly-i'ormed vhollow taper plug fitting the internal taper of the said barrel and communieating with the interior of the bolster.

2. The combination of a spindle-case, a hollow tapered barrel screwed therein, a receptacle or reservoir having a hollow taper plug, the said plug being fitted and capable of rotating within the barrel whereby the reservoir may be put into a position to permit the oil to iow from or into the interior of the spindle-case as required as described.

3. The combination with a spindle case bored transversely throughk its walls with taper holes, of a receptacle or reservoir having a hollow tapered plug fitted and capable of rotating in the holes formed in the spindleoase together with the receptacle for the purhaving a joint adapted to prevent escape of 1o pose of discharging or` supplying oil to the inoil at such joint regardless of the extent and terioi of the said 'case as described. direction of rotation.

4. A combined bolster-casing and oil-i'esei'- In testimony whereof I have affixed my sigvoir having a supplemental oil-reservoir dinature in presence of two Witnesses. reotly and rotativelyconneoted therewith and THOMAS ERNEST LEIGH. adapted to he turned from an upper to a Witnesses: lower position to enable oil in the reservoir.- JOSEPH NASMITH, to be discharged, the relatively movable parts LEONARD HORNER.
